That's where I stopped reading and rolled my eyes so hard my head hurts.
Don't play on servers where you should be killing people and/or playing objective if you want to friendly. We have servers available that allow it. GO THERE.
This is mostly for TF2, but I've seen it happen in a few other games too. There will be a friendly group waltzing around, but one person usually decides to start going try hard and killing the friendlies. Why don't they just leave and join a different server with actual fighting going on in the game?
Why not? Is it against the rule to be playing the game?
Why don't they go leave the server and join a friendly server? Skial servers have a rule against friending as Skial servers are for people who want to play the game. Skial pays for the servers so Skial makes the rules.
